BUNDLING-MACHINE.

To all whom it may concern.

Be it known that we, CHRISTOPHER J. Mo- GAN and CHRISTIAN B. ANFINDSEN, citizens of the United States, and residents of Charleroi, in the county of Washington and State of Pennsylvania, have invented a new and useful Improvement in Bundling-Ma chines; and we do hereby declare the following to be a full, clear, and exact description thereof.

Our invention relates to bundling machines, for compressing into bundles and securing by tie bands such material as wire in coils, straight wire, rods, band iron and other articles. Heretofore the operations in preparing bundles of the above mentioned material were performed by hand. Inbundling coil wire, particularly, two employees are generally needed, and the operation of stretching and twisting the tie band by pliers is necessarily slow and tedious labor, with resultant irregularity of bundle and great waste of tie material. I

The invention is devised primarily for performing the above operations automatically, so as to give uniformity and rapidity to the steps ofthe operations,with uniformity of bundle and increased output. Afurther object is to provide a machine which is adjustable to a wide range of bundle sizes, which may be employed as a single machine for some kinds of material, or arranged as a single unit in a machine comprising several such'units for bundling long material, such as rods or the like.

A further object is to provide a machine of the above character in which the material is compactly pressed to form a symmetrical bundle having a tie band of minimum length. The bundle'so formed resulting in a saving of tie material and in bundle space for storing or shipping.

The invention consists in the novel con-- struction, "combination and arrangement of parts hereinafter described.

.In the accompanying drawings, Figure 1 is a side elevation of the machine; Fig. 2 is an end elevation; Fig. 3 is a front elevation of one unit forming half of the machine; Fig. 4 is an enlarged vertical sectionlotthe upper portion of one half of the machlne the section being taken on a line central with the Specification of Letters Patent. Application filed January 30, 1917. Serial No. 145,397.

Patented Apr. 2, i918.

'10 and 11 are detail views of the mechanism for moving the ends of the tie band in position for engagement with the twister jaws; Figs. 12 and 13 are detail-views of the holder for holding the cut tie band in position to be carried up around the bundle by the bundle elevating-jaw; Fig. 14 is an inverted plan view of the twisting jaws in closed position; Fig. 15 is an enlarged cross-section of a tied bundle.

The numeral 2 indicates the base orbedplate of the machine and is shown as a portable machine with Wheels 3. Upon the base plate is secured housings 4 which formthe frame for supporting all of the mechanism of the machine except the power element which in the instance shown is a motor 5 on the bed-plate 2. These housings are in duplicate, right and left, and have like mechanisms which operate in unison, and in describing the invention, we will refer to only one side of the machine.

Situated between the housings on supports 6 is the bundle table 7. Referrin now to Fig. 5, it will be seen that the ta le is formed'of two sections connected by extension rods 8 and each section is adapted to slide on the supports 6 for adjustment to support various sizes of bundles. The machine is illustrated as arranged for bundling coils of wire, such a coil being indicated at 9. The table for bundling this kind of material is provided with the radial supporting rollers 10. One of the housings of the machine is adjustable on the bed-plate so as to adapt the machine 'for various diameters of coils, the adjustment being effected through a screw 11 anchored to the bed-plate and having engagement with a nut in the housing. The screw is adapted to be rotated by caring 12 and hand-wheel12. This a weli-known form of construction for an adjustable screw-feed for various purposes,

and needs no further description in connection with this invention.

The loose coils of the wire are conveyed to the machine on a power carrier 13 which is a simple type of endless conveyer of any suitable structure. onto the table and pulled in position by the operator to be bound. In some cases, several of such coils, if they are thin 0011s or coils of short length, are stacked on top of one another to be formed into a single bundle of commercial size. a

Fig. 1 represents the-machine with a loose coil of wire resting on the table in position ready to be elevated by the upward movement of the compressor heads 15. The compressor heads of both sides of the machine 3 moving in unison carry the coil up into engagement with fixed compressor-jaws 16,

a when at the completion of the up stroke, the

tie band 9", which is also carried up with the bundle, is. tightly twisted to bind the coil in compressed shape; Two of such bands are applied simultaneously at one operation of the machine, and the bands are arranged diametrically opposite one another on the coil. At the down stroke of the compressorvheads, the bundle frees itself fromthe fixed jaws, and is lowered with the compressorheads where it again rests on the table rollers in position to berotated so as to present the bundle in a position for applying other bands; usually four bands are applied to a coil of wire, the bands'being arranged about equally spaced.

One unit, or one-half of the machine as employed for coil material, maybe used for.

bundling long straight material such as rods or the like, by feeding the rods longitudinally onto the compressor-head for each band applied. Or, several of suchunits may be arranged so as to have their jaws in= alinement,. whereby all of the bands are applied simultaneously. No illustrationiis shown of the units so arranged, but as here inafter described, it will be seen that the mechanism of each unit is such as to permit the units-to be arranged in line, orina row, and .driven to act in unison by driving from a single shaft through bevel gear connections, as indicated in dotted lines at A in Fig. 1 of the drawing; and it is to be understood, andincluded as part of our invention to have the units so arranged. I

The mechanism for accomplishing the 'op. erations of the machine is as followsn A power-shaft 17 driven by the, motor 5 or other suitable source .of power drives through sprockets and chain 18 18, a shaft 19, which, through direct bevel-gear connections 20, rotates the tie twister 'spindle'j21. Spur-gears 22, shaft 23, and bevelgears 24 drive a shaft 25"fromwhich power is taken The coils are delivered Idle to the elevated for elevating and compressingthe bundle. Shaft 25 drlves by pinion 26, a gear 27 on shaft 28. Movement for reciprocating the compressorehead is provided by connecting to the gear 27, a pitman 29, which connects by an arm 30 to a rock-shaft 31. A forked arm 32 -is secured to the rock-shaft, and connects by swinging link to a sleeve 33 on the compressor-head shaft 34. Referring to the enlarged view, Fig. 4, it will be seen that the compressor-head 15 is mounted on a screw 35 engaging the sleeve 33, and saidscrew provides means foradjustment to vary the length of the travel of the head for compressing various thickness of bundles, and or adjusting the head to position with different sizes of jaws employed, the jaws being of various cross-sectional shapes, and are removable. Rotationof gear 27 acts through the downward stroke-of the pitman to elevate the compressor-head to carry up the bundle and compress it. At completion of the downward stroke the arm 30 whichis provided with. a catch piece 30", engages a spring-held latch or holding-stop 36, which holds the elevated bundle momentarily at the beginning of the upstrokeof the pitman, while the tie-band is twisted. The delay period for holding is effected by providing play? at the connection of the pitman and arm, such as the elongated eye bearing 37 for the pin 37.

upstroke brings the tripper into engagement with the spring-latch, freeing the arm of the rock-shaft, and allowing the bundle to be lowered as the upstroke of the pitman con- Ihe pitman is provided Wlth a trlpper 38 which is so positioned, that, the'idle movement of the pitman on the tinues. -Wh en the compressor-head is in its loweredposition, the tie material is fed into the machine to a position beneath the bundle and cut off. The tiematerial isin a coil or on a reel, not shown, and passes through tension rolls before entering. the machine. The tie is thencarried by the bifurcated jaws of the compressor-head with the bunapplied by a twister. U y e Means for feeding the tie material into position to'be cut off and to be engaged by the. compressor-head comprise geared feedrolls 40 and 41. The shear for cutting the tie is indicated at 42. The tie as fed to position beneath the bundle lies above and position, and the tie is out of engagement with the normal low po-r sition of the compressor-head jaws, and? means, such as the holder 43 is provided for' i supporting the tie after being cut -by the T1 shear. This holder consists of blocks 44 and 45 supported on a bracket 46. The block 45 1s yieldableand is spring-held, so as to form a clamp with the other block for grip- P shown in Figs. '12 and 13.

the wire, details of which are clearly engagement with a ratchet-wheel 52 loosely journaled on said shaft. Said ratchet drives a gear 53 "whichlmeshesiwith a gear 54. on the shaft'55 to which the top feed-roll.

' is secured. Mean's'fordisengaging thepawl from the ratchet when the proper length of tie has been fed forward, consists in providing a guide ring segment 56 mounted on the housing-concentric with shaft 28 and having an adjustable end to form an open space 66" between the other end of the ring segment. The inside'diameter of the segmentv forms a track adapted to engage a roller 61" of the pawl, which rocks the pawl on its pivot out of en agement with the teeth of the ratchet. e open space of the segment permits the gawl to move to its natural spring-presse position to engage the ratchet. The length of the open space determines the length of the travel, or the time in 40 v is secured to a cross-head .brblock-57 secured shear block 58.

.band for various len v s Shaft 28 also provldes powerforoperatwhich the feed-rolls are rotated. This ring segment is provided with a movable section 56 which may be adjusted to lengthen or contract the openspace 56 of-the ring, to shorten or prolong the time of engagement of the pawl with the ratchet to feed the tie gths. w

The shear blade to rods 57" whic reciprbcatethrou h the he upper ends of 11%? rods are connected by a cross-head 57 and link 57 to an" 91111159 of a bell-crank"59 journaled on a'shaftiin*'the frame. The other arm 60c of the bell-crank engages with a "cam 60 on the shaft"28.f; The cam is adjustably mounted on the shaft to permit setting .to different positions for varying the time period of .throw."for moving the shear to cut difiere'nt lengths of ties-L Mechanism -j for binding the compressed bundle is clearly shown in the vertical sectionaLview, Fig. 6. r This mechanism in cludes the rotating spindle 21- which has the. head 21' to which is pivoted in oppositely" disposed position, a pair of 'aws 21. These jaws are connected by lin s to a sliding member 21, which is adapted to reciprocate on the spindle, and forms with thelinks a toggle-joint for moving the jaws to open and closed position. Figs. .6 and 7 represent the jaws in open position, and Fig. 8

in the closedposition. The sliding member is reciprocated by a forked arm 70 ournaled to the member to permit of rotation of the member with the spindle. Arm .70 is secured to a rock shaft 71, which is rocked by cams 72 and 73, secured to shaft 28, said cams engaging the rollers of arms 74and 75 respectively, secured to shaft 71.

lDuring the feeding of the tie band, and.

while the compressor-head is elevating the bundle, arm 74 is engaged by the delay face 72 of cam 7 2, which keeps the sliding member elevated and the tie gripping-jaws open to receive the ends of the tie band. The tie band is stripped from the holder 43 as the compressor-head moves up, and is forced into the cavity L5 of the jaw of the comress or-head, as clearly shown in Fig. 6.

en the bundle has been moved to compressed position, the free spreading ends of the tie band are brought together as in Fig.

7, so as to be engaged by the gripping-jaws of the twister. Means forclosing the ends 7 of the tie consist of two horizontal sliding plates and 81 mounted to slide in guides 80 on thefixed compressor jaw, as clearly shown in Figs. 9, 10 and 11. These slides are actuated by a cam 82 on the shaft 28. A roller arm- 83' engaging the cam is adapted to slide in. a fixture fast to the housing and has a rack 84 which rotates a pinion 85.

Pinion=85 through rack engagement 86 and arm connection 87, reciprocates slide plate 80. Plate 81 is provided with-a rack 88 which meshes with a pinion 89 fast to shaft 90 to which pinion 85 is secured. Reverse direction of motion of the plates is effected by locating the pinions between the slide 'racks. The plates are returned to their open positions by means of a spring 83.

When the bundle has been moved to compressed position, cam 72 ,has moved to free the holding arm 74 and at the same time, cam 73 engages the roller of arm 75, moving the arm up and rocking the shaft to lower the sliding member 21'. The sliding memher in lowering, closes the tie gripping-jaws. These jaws'have- V-shaped gripping faces 21 and in closing draw the ends of the wire centr al with the rotating spindle in which positlon the revolving jaws twist the bands tightlyto bind the bundle. The jaws remain closed while the arm 75 engages the delay face73 of-cam 73.

From the foregoing description of the machine and its operations it will be seen that,

bundling of material may be done. rapidly and with uniformity of bundles, and the wide range of adjustment brings many dif 'ferent sizes of bundles within the scope of the machine. While the machine is designed. primarily for bundling coiled material such as coil wire or the like, of substantially circular cross sectional shape of bundle, the

invention is by no means restricted thereto. It will be apparent that material may be bound into bundles of various cross sectional shapes by simply changing the shape of the recess in the compressor jaws, and making the jaws in the fixed compressor-head 16 removable, inj-the same manner as they are removable in the lower compressor-head. Also, it will be apparent that when the units of the machine are used for bundling long straight material suchas rods or the like, other forms of table or bundle support may be employed without departing from the principle of my invention.
